Abstract
The HMS(hydrologic modeling system) model is one of the most used model thanks to its capabilities and panoply of modelling formalisms. However, more effort should be done to facilitate the estimation of initial values of parameters of the HMS model. In this article, we propose a comprehensive approach to estimate initial values of the parameters of the HMS formalisms. The formalisms concerned are the five loss methods, the simple canopy method and the simple surface method. The approach use data of the African soil grid 250m data for parameters estimated based on soil properties, a supervised classified ETM+ satellite image for parameters needing land use characteristics and the daily discharge for parameter demanding stream flow recession analysis. The basin of Bin El Ouidane was chosen as a case of study, in order to assimilate the estimation approach and the data utilization.
